Microsegmentation has been around for a long time, and it’s now used to regulate the communication between segments. In modern networks, this technology can be applied in order not to allow cross-network traffic or certain types of applications from one network segment to communicate with other servers/applications located elsewhere on your own internal walls.
Microsegmentation is a great way to group your data center’s workloads according to their characteristics, making it easier for you and other users who don’t know about these policies. This can help by allowing intelligent grouping of resources so they are more easily recognizable as belonging in one category or another.
With the rise of containerized and cloud-native architectures, micro-segmentation is changing. Traditional segmentation solutions cannot scale in these environments due to their dynamic nature that forces security measures into place at every turn with little flexibility for enforcement or update options.
A problem that new technologies have started solving is discovering endpoints throughout Kubernetes clusters as well as defining policies from those findings and then applying them automatically without constant intervention on behalf of user activity preferences who may be logging in constantly between different devices.
The Importance of Microsegmentation

In a world where cloud-native architecture is the norm, not only do we have to worry about network segmentation but also how it will affect our security practices. New micro-segmentation is emerging that provides visibility and control in this increasingly complex environment for both organizations struggling with traditional solutions as well those looking into new ways of managing their data center infrastructure altogether.
The need for a data center perimeter has never been greater. The old model of protection is being phased out as BYOD policies continue to grow in complexity and east-west traffic within the network increases exponentially. It is making it increasingly difficult to defend one central point from external threats like hacking which can now come via any device connected wirelessly across different networks without even being near an actual wall outlet.
Executing Zero Trust Policy along with micro-segmentation
Zero Trust and micro-segmentation are designed to give organizations the ability to stop malicious attacks before they happen. The cybersecurity landscape has become increasingly complex, which makes this crucial for businesses of all sizes in order to protect themselves from becoming a target or victim of hackers.
To minimize the risk of cyber threats, organizations must implement a zero-trust approach to security. Zero Trust policies restrict access and resources so employees can only utilize data needed for their tasks, this includes restricting what applications they have available too.
After an employee is authenticated, any requests they submit to the network must be evaluated according to predefined access control policies and either permitted or blocked. Likewise, applications should only be provided access according to business logic and limited to the minimum required privileges.
Microsegmentation is an essential component of any zero-trust architecture because it allows you to create boundaries between all workloads and enforce tight access controls. In the event that there’s a network breach, attackers’ ability will be greatly reduced by Micro Segmentation’s existence within your organization’s systems.
4 Best Practices of Microsegmentation
Define Authorization Levels
To provide a consistent user experience, it’s important to use the least-privilege approach and start with the lowest privilege levels. This will allow your application’s services for each group or category of users without any overlap in access rights which can result from having too many administrators on one server instance running simultaneously.
Configure Policies
With our policies, you can tailor your security configuration to meet the needs of any business. You’ll have complete control over who sees what and when they’re visible with these tailored settings that are specific for each asset type such as servers or applications.
Set Limits
Microsegmentation is a type of security that allows you to identify the desired limits for your applications, which determine what information can be exchanged. Define these objectives according to business needs and categorize or distinguish end users so they are only accessing relevant content on separate sites with minimal overlap in order to create an effective defense against cyber threats.
Verify Application
When it comes to your security policies, the best way is by simulation testing so you can identify and address any gaps in implementation.
